Problems solved by technology

[0002] Acrylic paint and gouache paint are two completely different types of paint for art painting. The former has the characteristics of quick drying, bright colors, water resistance and weather resistance, and can be stored for a long time, but the price is relatively high, and due to the characteristics of the paint itself, it is transparent. Or translucent colors are mostly, and the hiding performance is poor; while gouache pigments are characterized by strong covering power, rich and changeable colors, the finished quality is atmospheric and stable, and the price is low, which is more acceptable to ordinary painting lovers, but it is water resistant. Relatively poor weather resistance, not easy to store

Embodiment 1

[0013] Embodiment 1: a kind of acrylic gouache paint, based on the total weight of the finished color paste, its formula consists of:

[0014] 35 parts of acrylic emulsion, 30 parts of barium sulfate, 5 parts of kaolin, 10 parts of fast red, 15 parts of thickener, 2 parts of preservative, and 3 parts of defoamer. The above materials are prepared into acrylic water pink paste through the following steps:

[0015] (1) Accurately weigh each material according to the formula dosage of acrylic gouache

[0016] (2) First, grind and disperse the colorant with a ball mill until the particle size is less than 25um

[0017] (3) Add acrylic emulsion, colorant, filler, additives and other components to the high-speed disperser in turn for dispersion

[0018] (4) After complete dispersion, grind the color paste with a three-roller high-speed grinder to obtain acrylic gouache product.

[0019] After testing, the finished color paste has a pH value of 8.5-9.0 and an average density of 1.30...

Embodiment 2

[0020] Embodiment 2: a kind of acrylic gouache paint, based on the total weight of the finished color paste, its formula consists of:

[0021] 45 parts of acrylic emulsion, 20 parts of calcium carbonate, 5 parts of talcum powder, 15 parts of titanium dioxide, 10 parts of thickener, 2 parts of preservative, and 3 parts of defoamer. The above materials are prepared into acrylic water pink paste through the following steps:

[0022] (1) Accurately weigh each material according to the formula dosage of acrylic gouache

[0023] (2) First, grind and disperse the colorant with a ball mill until the particle size is less than 25um

[0024] (3) Add acrylic emulsion, colorant, filler, additives and other components to the high-speed disperser in turn for dispersion

[0025] (4) After complete dispersion, grind the color paste with a three-roller high-speed grinder to obtain acrylic gouache product.

[0026] After testing, the finished color paste has a pH value of 8.5-9.0 and an avera...

Abstract

The invention mainly relates to a formula of a novel drawing material, propylene gouache and a preparation method thereof. One technical scheme is that the formula comprises the following components in percentage by weight: 35-45% of acrylic emulsion, 25-35% of filler, 10-15% of coloring agent, 10-15% of thickening agent and 5% of other auxiliaries. Another technical scheme is a specific preparation method of the novel drawing material. Due to the technical schemes, the propylene gouache integrates the advantages of propylene pigment and gouache and is remarkably improved in terms of water and weather resistance, drawing texture, opacity and the like while the cost is relatively low; and therefore, the propylene gouache is quickly accepted by the market more easily so as to form scale merit.
